EDWARD B. NOWOSIE'LSK I, OF BLOOMFIELD, NEW JERSEY, ASSIGNOR '10' SPLITDORF ELECTRICAL COMPANY, OF NEWARK, NEW JERSEY.

uaemrro CONSTRUCTION.

Application and October so, 1920. Serial No. 420,646.

To all whom it may concern:

Be it known that I, EDWARD B. NOWOSIEL- SKI, a citizen of the United States, residing at Bloomfield, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Magneto Constructions, of which the followin is a description, reference being had to t e accompanying drawings and to the figures of reference marked thereon.

My invention relates to magneto construction and has for its object a magneto of compact construction in which all available space is utilized so as to reduce the overall len th of the magneto.

nother object is to mount the commutator or distributor spool as far as possible from the bearings so as to prevent oil, dust, eto., from reaching the same.

Still another object of this invention is to so place the distribnter spool and brushes so as to be out of harms way when openin the magneto for inspection or repairs.

%ther objects will appear after reading the specification and claims.

In the drawings which illustrate one embodiment of my invention--- 7 Figure 1 is a view of the improved magneto with parts separated and the rotor partially withdrawn.

Figure 2 is a medial section therethrough, the rotor being in place and a Figure 3 is a plan view of the underside of the base of my ma etc;

My magneto is of t e type disclosed in m application Serial No. 365,305, filed Marc 1 1920, and comprises a cast non-magnetic base 1 within which is embedded long laminated side ole pieces 2 and 3 and top pole pieces 4 and 5 shown in Fig. 1, there being a space left between the top pole pieces. In engagement with the top pole pieces is a bridging laminated core piece 6 about which is wound the induction coil 7 having the usual primary and secondary windings. To retain the core 6 in lace two straps 8 are provided which straddle shouldered portions 9 of *the core piece and which are secured to the casting 1 by screws 10 or other suit able means. Positioned on the pole pieces 2 and 3 are the permanent magnets 11 and 12,

Within a bore 13 in the base there rotates a rotor 14 having two sets of inductors 15 and 16, 17 and 18 respectively set at right angles to one another and separated by a space medial of the rotor hitherto not utillzed but within which accordin to the present invention is situated the dlstributer spool 20 of ba'kelite, americanite or the like having a commutator segment 19 embedded therein. This distributer spool is about midway between the end bearings of the mag neto.

In contact with the distributor spool there is a brush 21 spring pressed from a brush holder 22 inserted in between the pole pieces 4 and 5. The holder is maintained in place by means of two screws 23 passing through the base 1 and threaded into the holder as is clearly shown in Figs. 1 and 2. Within a recess in said brush holder there abuts a secondary terminal 24, the other end of the secondary being grounded to the frame at fipy convenient point as to the core mem- Inserted through the bottom of the base and held in place by means of two screws 25 is the spark plug connecting block 26 Carryin two brushes 27 inclined toward each ot er, each resilientl mounted within a conducting member 28 aving a socket connection 29 adapted to receive a plu connector P which may be inserted throug openings 30 in the base of the ma eto. The base is also provided with two oles 31 to fit over positioning pins on the magneto retaining su ort.

o enclose the. magneto non-magnetic cover plates 32 and 33 are provided, spaced from the magnets by means of felt or other gaskets 34 and 35, and mounted so as to clamp these cover lates to the base are the bearin and end p ates 36 and 37 which are secure to the base bz means of screws 38 which pass through t e bearing plates and cover p ates and which are tapped into the base .1, shims 39 being interposed as is found necessary. 7

U on the bearin plate 36 is mounted the brea or box 40 wit in which is mounted the breaker mechanism, not shown, operated by the cam on the magneto shaft as is the common practice. A wire 41 connects one end of the primary to one of the contacts of the breaker mechanism, the other contact, the breaker mechanism and the other end of the primary being conveniently ounded.

Having thus described my lnvention, what I claim is:

1. In a magneto construction a magneto too base, a rotor within the base, a distributer spool located on said rotor within the confines of the base and brushes mounted in the base in contact with the distributer spool. 2. In a magneto, a magneto base, a rotor mounted within the base, said rotor having two sets of inductors, one set at each side of the medial line of the rotor, a distributor spool between the sets of inductors and brushes situated within the base of the magneto engaging the distributor spool.

3. In a magneto, a magneto base, pole pieces in said base, additional spaced apart pole pieces in said base, a brush and brush older in between the spaced apart poles, a rotor within the base, a distributer spool on said rotor in position to be engaged with the brush, and additional brushes inserted through the base of the magneto in engagement with the distributer spool.

4. In a ma eto construction, an interiorly located distributor spool, an interiorly located brush mounted in a block situated within the base of the magneto and in contact with said distributer spool, an electrical connection for said brush terminating in a pin and socket connector, said connector extending laterally from said block, and openings in said base aligned with the connector in the block to enable the connection of a conducting wire with the pin and socket connector.

In testimony whereof, I afiix m signature.

EDWARD B. NOWOS ELSKI.
